    Is there one right now that’s likely to be commercially viable soon? No. Can there be one? Probably. Technology, especially green tech, is developing rapidly. You can never really put a limit on technology. In fact, an ESL (electron stimulated luminescence) could be better than LEDs, though they are still being developed.
